Oblation is a guaranteed buy, and the creatures siege-gang commander, twilight drover, and geist-honored monk are all cheap and could potentially be worthy additions. Though maybe someone has other thoughts on them.

Earthcraft and Elesh are a bit much $ for right now though I know a guy who might give me a deal on Earthcraft, Craterhoof and Position are a little more reasonable, I could grab both and still have spare for some other stuff.

One card I can't decide on is Mirari's Wake, it looks really good, but not sure if it would really be worth the $6, as I have other pumps and mana ramp. also not sure if I really want Mana Echoes, I don't usually go infinite. And I'm thinking Aurelia wouldn't be too necessary if I grab Craterhoof.

Sterling Grove? Tutor would be nice, but if I get Privileged Position I could cross it off or maybe just grab Replenish...

tl;dr I've got $30 and I'd be very interested in any suggestions as to what cards people think would be the best investment, both monetarily and in terms of bettering the deck.

EDIT: Decided I'm going to grab everything except for Boundless Realms which I don't want and Privileged Position, Elesh Norn, and Mana Echoes. I have a potential trade deal for an Earthcraft so I might go for that, but otherwise I'm going to hold off on infinite combos until I feel I really need it, Elesh Norn will be mine soon though. And Position soon as well, next $30 boom both of them.

Are you against the inifinite combo with this deck? [[Mana echoes]] and (the name escapes me) its a cmc of 5 (3WW) and it says that whenever a creature hits the battlefield all your dudes get a +1/+1 counter.

Hey thanks for responding, So, let me ask you, do you think [[Boundless Realms]] could be a decent alternative to Mirari's Wake? they're not exactly the same, but Realms essentially doubles my mana and it's only $1 compared to $6

I have Cathar's Crusade which would let me go infinite, but idk I might put my money elsewhere, I'm not necessarily against it though.

Also, maybe you don't have an opinion, but since you're the only person to reply, let me ask you, should I grab a [[Craterhoof Behemoth]] or [[Aurelia, the Warleader]]? Would both be overkill?

Trust me. Mana echoes is a must have. Your boardstate will get hilarious with it on the field.

Edit: in response to craterhoof/aurelia: both are great but I don't personally run them. I prefer Purphoros, god of the forge. Cheaper than craterhoof in cost and price and it allows me to win on the spot once hes on the field and im making a lot of tokens with Marath.

If you have the 7 mana to cast Boundless Realms, you should already be able to cast most of your deck, unless you plan on having tons of basics and using big x spells. Aurelia is cool but Craterhoof usually says I win right now gg no re.

In your Maybeboard the cards Elesh Norn, Craterhoof Behemoth, Aurelia and Momentous Fall are probably the best cards to pick up (Earthcraft is really good if you go more into combo). Of all of these Momentous Fall is the easiest to get at around $0.80 and card draw is always super good. Combining Momentous Fall or Greater Good with a Xenagos, God of Revels is pretty nuts, you should take a look at him as well.

Mirari's Wake is pretty insane with the deck and is definitely worth it. Marath is a gaping mana hole that will absorb as much as you can spend. For extra fun toss in cards like Genesis Wave along with it (although Genesis Wave would require running more permanents than you are currently). Mirari's Wake just got reprinted in Conspiracy, so it is cheaper than it used to be.

Mana Echoes is only really good if you are comboing off or already winning. Any other case and it's pretty bad. I go back and forth with it, but it's currently not in my list.

I'd shoot for a Swords to Plowshares as it's super cheap right now (thank Conspiracy for that again) and is one of the best removal spells ever printed. I'd cut either Selesnya Charm or Naya Charm for it.

A good mana base is important, you should take a look at the check lands: Sunpetal Gove, Rootbound Crag and Clifftop Retreat. They are pretty cheap relative to other lands of their quality. Shock Lands are about as cheap as they'll ever get right now, so it might actually be best to just spend your entire budget on them. Not really a fun purchase, but you'll be glad later.

Here is my list by the way. I've replaced all of my combo cards with silly cards like Kzzuul, Tyrant of the Cliffs because I'm silly. I think Momentous fall is better than Life's legacy, I'm just testing it out because it has a lower mana cost.
